Night Sky on Mars

Stunning! An 8-hour time-lapse to show the Earth is rotating while capturing the Milky Way.

Does the Universe expand faster than the speed of light? Just 13.8 billion years after the hot Big Bang, we can see 46.1 billion light-years away in all directions. Doesn't that violate something?

Does the Universe expand faster than the speed of light?

The Universe is expanding, and ever more distant objects appear to recede faster and faster.

At some point, they exceed the speed of light.

And yet, relativity is just fine with that.

Even remote, high-altitude (almost 14,000 feet) telescopes like Gemini North on Maunakea can’t escape light from satellite constellations. While invisible to us, they leave bright streaks in sensitive long-exposure images. @aura-astronomy.bsky.social #astronomy GeminiObs/NOIRLab/NSF/AURA/J. Pollard

Your daily dose of cosmic perspective… 🔭🧪

After 3 1/2 month break we're back on track with the SeestarS50 here at Glemsford, Suffolk, UK. My alt astrophotography base which gives me good views of the Northern sky and Bortle 4/5.

Hoping that there will be a clear sky at 10pm onwards🤞🔭

a red emission nebula looks like a flying bat. between the wings is a squid shaped blue emission nebula. Image created from the best 245 of 352 5-min exposures through h-alpha and O II filters taken with a Takahashi TSA-120 with a 0.7x reducer and ZWO ASI2600MM camera. It is a 2-panel mosaic with the upper panel starting at the bright star in the center.

This 2-panel HOO mosaic took awhile! The Flying Bat Nebula (Sh2-129) and The Squid Nebula (OU4). The very faint OU4 was discovered by amateur Nicolas Outters in 2011. Triple hypergiant star system HR8119 (center) energizes the bipolar outflow of oxygen to glow blue. #astrophotography Details in ALT.

IC 434, the Horsehead nebula, is a dark nebula located about 1400 ly away in the constellation of Orion.

The unusual colour in this image is due to the hydrogen alpha spectral line being mapped to the green channel. #astronomy

A photo of a dense region of stars. There are a few areas with dark dust clouds and a smallish looking open star cluster as well.

Here is a portion of Messier 24, the Sagittarius Star Cloud, which is mostly just a vast number of stars with some dark dust. There's an open star cluster, NGC 6603, visible just above the red star, right of center. 🔭

Interesting solar surface these past few days. No huge active regions but a great pattern of little ones. I was just so thrilled to see the sky. I had to take an image of something. #Astronomy #Astrophotography

A perennial favorite: the Lagoon Nebula! #astrophotography #astrosky #milkyway #nightsky

Sharpless 119, is a large patch of emission in the constellation Cygnus and lies some 2200 light years away. It’s only 2-3 degrees away from the North American and Pelican Nebulae, so is often overlooked.

The Flying Bat Nebula (SH2-29) and the Giant Squid Nebula (Ou4, ) in Cepheus at ~ 2300 ly distant from Earth. The Bat is large H-alpha emission while the Squid is a faint Oiii-emitting object. The scope exposure period was 10 hours over 4 nights for this photo.

A vivid image of the Crescent Nebula (NGC 6888) in deep space, surrounded by swirling clouds of red, pink, and purple interstellar gas against a dark starry background. The nebula appears as a bright, glowing, shell-like structure near the center-right, with filamentary textures and intricate patterns of light.

The Crescent Nebula and some of the surrounding nebulosity.

Capture details: Celestron AVX mount, Apertura 60mm FPL-53 doublet with flattener, Optolong L-enhance filter, ZWO ASI2600mc pro, and ZWO ASI120mm mini guide camera.

A bright streak is pictured through a starry sky over a beach spotted with the husks of dead trees. The rollover shows the resulting smoke trail from the bright meteor.

Jersey Skies: The Milky Way spills across the evening sky This is a great time of year to look for the Milky Way. All the stars we see at night of course are part of our Milky Way — the huge collection of gas, dust and stars that we live inside.

Check out this incredible image of the nebula forming around a pair of Wolf Rayet (= very massive) stars - taken with #JWST + MIRI at 7, 15 and 25 µm. So gorgeous. 🔭

I was so excited abut the prospect of a clear night here at the coast. But the fog only stayed out for an hour. This is what I got. Wide field M8, the Lagoon Nebula, and M20, the Trifid Nebula. Tonight I'll go out to DarkSkyLand and shoot the same thing but for longer. #Astronomy #Astrophotography

Infrared observations of a baby star and its burgeoning planetary system. In orange, we see the distribution of carbon monoxide, blowing away from the star (center) in a butterfly-shaped wind. In blue, we see a narrow jet of silicon monoxide, also beaming away from the star.

This is the East Veil Nebula. It is located 2400 light years from earth. I always think it looks like a creepy face to me! #astronomy #astrophotography #space @kat-astro-bot.bsky.social
